Dual NAND flash drive not working

Paulo Steigleder

I'm trying to implement a dual NAND drive using an MT29F1G08. Drive N0 works ok, but drive N1 didn't work, even configuring it on File_Config.c. I try using finit(NULL) to initialize both drives, but checking on low level routine I found that NAND_DRV_CFG.DrvInst is always 0x00 (meaning that only drive N0 will start).

    Find and open File_lib.c and take a look at line 524 - change the numeric zero to one. Your structure should look like this:

     /* NAND Flash Configuration */
 static NAND_FTL_CFG nand1_cfg = {
   /* NAND Flash Geometry */
   { &nand1_dev.PgLay,
     NAND1_BLCNT,
     NAND1_PGCNT,
     NAND1_PGSZ,
     NAND_SEC_BLOCK (NAND1_PGCNT,NAND1_PGSZ),
     NAND_SEC_PAGE (NAND1_PGSZ),
     NAND_ADDR_CYCLES (NAND1_BLCNT,NAND1_PGCNT,NAND1_PGSZ),
     NAND1_SWECC,
     1
   },

    Does this work for you?
